Abstract

This paper is aimed at finding the optimal locations of collocated actuator and sensor pairs for active vibration control of cable-network antenna reflectors. The front cable net of the antenna is considered as the control plant. The optimal criterion for placement of actuator and sensor pairs is to choose locations that simultaneously maximize the H2 norms of each dominant mode, and simultaneously minimize the H2 norms of the residual modes when spillover effect is considered. Direct velocity feedback is applied to verify the effectiveness of the optimized locations. Numerical simulations indicate that the method proposed in this paper is feasible.
